He was only an asshole to Nevile because easily, that night, Nevile could have been the one that Voldemort had cast the killing curse on, and love having saved him as it did Harry. And this happened before Voldy went to the Potter's, so then he never would have killed Lily, cause, ya know. He would have been "destroyed" or however it was explained. I don't remember exactly.

SO then Lily's life would have been spared if it had been Nevile becoming The Boy Who Lived instead of Harry.
So I can see where his anger is coming from, although uncalled for, for both of the boys.

Ya... he got away with a lot thanks to black and white morality kicking into gear...

HP is a great series that could have been a lot greater if it just tweaked things a bit here and there... like not making hufflepuff that house that nobody belongs to except that one guy who died... and making slytherin a genuinely ambitious house and not just a house full of assholes....

Hermione was a mary sue... Harry was a little too self involved for my liking... Best characters were Sirius and the Weasleys because they had hard lives but dealt with it instead of bitching about it.

In Order of the Phoenix, Harry's room in the invisible house (I forgot what it was called) had a painting that had the last Slytherin headmaster in it. Harry was going to fly away and the painting sent a message from Dumbledore telling Harry to stay put. Then, when Harry started whining the painting reminded him that listening to Dumbledore kept him alive. Then, Harry sulked in his room for a few chapters.
